Looking for DAC for mac min 2000$

If you buy an Antelope Audio Zodiac you can use its volume control as a preamp as well. Plus, its a great sounding DAC with a lot of options for inputs and outputs. The Zodiac + has an analog input as well and is available used for $2000.

im selling an M2 Tech on Ebay, i cant post link here but you can search for M2 Tech or my username pearlcfam.

if you've considered using firewire, you should absolutely checkout the Weiss DAC2. Used price is right in your wheelhouse.
